Abstract:The paper presents a statistical process control method for monitoring health-recovery processes described by short non-stationary time series. Shewhart control chart for residuals, based on model averaging approach, is built for differences between values of consecutive observations. Practical applicability of this new approach has been demonstrated using a real-life example of a recovery from a blood mild hypertension episode.
